“Concerning the importance of the Atonement, in Alma we learn, ‘For it is expedient that an atonement should be made; … or else all mankind must unavoidably perish.’
If you have made no mistakes, then you do not need the Atonement. If you have made mistakes, and all of us have, whether minor or serious, then you have an enormous need to find out how they can be erased so that you are no longer in darkness.
‘[Jesus Christ] is the light and the life of the world.’ As we fix our gaze on His teachings, we will be guided to the harbor of spiritual safety.”
Boyd K. Packer, “The Atonement,” November 2012 Ensign
